To all whom it may concern Be it known that I, ELIJAH C. RINNER, citizen of the United States, residing at; C0- shocton, in the county of Goshjocton and State of Ohio, have invented certain new and useful Improvements in Paper-Corrugators, of which the following is a specification.

My invention relates to that class of machines designed for corrugating -strawboard ?"paper from which corrugated paper 'and pasteboard is commonly formed, and

the invent-ion has for its primary object the provision of a very' simple, effective and easily operated mechanism by which one layer of paper or board'may be corrugated and an outer facing applied thereto;

Another object of the invention is to provide means whereby the corrugating and pressing rolls may be adjusted toward or from each other to-secure more or less pressure against the paper bein treated.

A still further object is t e provision of means whereby the paper may be stripped from the upper corrugating roll, carried down between the second corrugating roll and the paste-applying roll and be stripped from the paste-applying roll and held so smoothly upon the corrugating roll that the paste will be applied equally over its whole area.

A further object is to rovide means whereby the paste may be easi y applied to the paste-applying roll so that it shall be evenly applied to the corrugated paper.

Other minor objects of the invention will appear in the course of the following description.

My invention is illustrated in the accompanying drawings wherein: I

s Figure 1 is a front elevation of a machine embodying my improvements. Fig. 2 is a side elevation thereof. Fi 3 is a section on the line 3-3 of Fig. 1. ig. 4 is a detail sectional view of the corru ating rolls, illusi rolls and pressing rolls, respectivel trating the action of one o the strippers.

Corresponding and like parts are referred to in the following description and indicated in allthe views of the accompanying drawing by the samereference characters.

My improved mechanism includes oppositely disposed supporting standards 2. which may be formed in any desired manner and which are spaced from each other and held in proper engagement with each other by transversely extending beams and Specification of Letters Patent.

spaced from each other a distance equal to the length of the corrugating rolls and the tie rods, these supporting. standards being atively fixed journal box for supporting a corrugating roll and with shiftable journal boxes above and below the fixed journal box for supporting the upp most and lowermost rolls, respective y. In detail, each standard is. formed with guides 3 formed by vertically slotting the standards within which guides are shiftably mounted I the journal boxes 4, 5 and 6. The journal box 4 is rigidly engaged with the standards in any adjusted. position by means of the set screws 4, these set screws permitting the journal box4-to be adjusted'up or down upon the standards. j

The uppermost journal box 5 is supported upon the journal box 4 by means of adjusting screws 7 and this journal box 5 maybe forced downward toward the journal box 4 by means of the adjusting screw 8 which extends through the upper end of the standard. By rotating this screw 3 in a reverse direction and rotating the screw 7, the ressure between the uppermost and the mlddle corrugating rolls may be adjusted.

The lowermost journal box 6 is likewise adjusted toward or from the middle journal box by means of an adjusting screw 8' which passes through a transverse web 9 extending across the space between the guides'et. Adjusting screws 7' are also interposed between the journal box .6 and the box 4. -Thus the pressure between the, rolls supported uponthe journal boxes 4 and 6 may be properly adjusted. It will be seen that this adjustment is positive'and that the pressure between the rolls supported by the journal boxes may be very delicately adjusted. These journal boxes may be made in any suitable manner and support the shafts 9, 10 and 11 of the upper corrugating ing roll 13 which is also provided with lon-.

gitudinally extending corrugations designed to mes 'with the corrugations on the roll 12. The shaft 11 supportsa roll 14 which has a smooth exterior face and is designed as a pressing roll. All of these rolls,

12,13 and 14 are hollow and are connected to suitable means whereby the steam may be conducted into the interior of the rolls Mounted upon the supports 2 is the paste trough 16. This'trough extends toward the roll 13 and is upwardly bent. as at 17 at its forward edge, this upwardly bent side 17 of the paste trough extending upward between the roll 13 and a paste-applying roller 18. This paste-applying roller is mounted in any suitable manner upon the trough 16 and dips into the trough.

The roller 18 is formed with a plurality of circumferential grooves 19 which aline with the grooves on the roll 12. The faces of the rolls 13 and 18 are in approximate contact. Mounted rearward of the roll 18 is the spreading roll 20 which is designed to distribute paste or like adhesive material over the surface of the roll 18'and to prevent the roll 18 carrying too great an amount of paste.

Mounted on a transverse bar 21 extending between the standards are a plurality of strippers 22, thesev strippers consisting of wires, each at one end coiled around the rod 21, then extending rearward and downward between the rolls 12 and 13 and in the grooves 15. The grooves in these rolls 12 and 13 are slightly deeper than the diameter of the wire used to form the stripping fingers or strippers. These wire fingers or strippers extend rearward and downward over the roll 13 and downward between the roll 13 and the paste-applyin roll 18 and are attached at their lower en s to a transverse rod or bar 23 which extends between the standards immediately in front of the paste trough 16. The downward extensions of thestripping fingers or wires 22 act to hold the paper passing over the'corrugating roll 13 in close contact with the roll 13 and thus hold the paper relatively flat so that the paste-applying roll will contact evenly over the whole surface of the paper with the crests or ridges of the corrugations, thus applying thepaste uniformly to these crests or ridges.

' It is to be noted that the stripping wires 22 do not have as great a curvature as the rolls 12 and 13. It is to be noted that the upper ends of the stripping'wires 22 are curved to conform to the curvature of the roll 12 and that the lower ends of the stripping wires or fingers 22 correspond to the curvature of the roll 13 but do not touch the roll 13 but rest within the grooves 19 of the paste-applying roll 18. These stripping fingers or wires first act to 'strip the paper after it is corrugated from the uppermost corrugatin-g roll and guide the paper over the lower corrugating roll, thus preventing the paper sticking to the upper corrugating roll and any tendency of the paper .to follow the upper roll. After the paper has passed onto the lower corrugating roll, the said fingers act to hold the corrugated paper to theroll 13 and also act to keep the paper from rumpling or becoming wrinkled and thus permit the paste-applying roll to apply pa'ste uniformly to the crests of the corrugations.

Supported upon arms 23 projecting from the standards 2 is the paper reel shaft 24. This reel shaft is designed to be passed through the center of a roll of paper or cardboard to be corrugated. This shaft is screw threaded at opposite ends as at 25 and provided with centering chucks 26.

These centering chucks have screw threaded nuts 27 which engage with the screw thread-- ed portion 25 whereby the chucks may be adjusted along the shaft 24 so as to accommodate rolls of paper having different widths;

The paper from the roll 28 supported upon the shaft 20 is carried over a guide roller 29 which extends along the front of the machine, this guide roller being so located that the sheet of paper 30 passing thereover is supported below the transverse rod 21 supporting the stripping fingers and in such position that the paper may move. .easily between the corrugating rolls 12 and 13.

It will be seen from Figs. 2 and 3 that the paper 30 passes beneath the forward ends of the stripping fingers 22 and that as the paper passes out of the stripping rolls, it will still be beneath said fingers and that said fingers will prevent, the paper after it is corrugated from sticking to and following the pathof the" upper corrugating roll 12 and will guide the paper downward over the corrugating roll 13. The sheet of paper 30 passes over and around the corrugating roll 13 and there comes in contact with a paste applying roller 18. Thus paste is applied to the surface of the aper.

The sheet 31 comes from a ro 32 mounted upon a spindle or shaft 33 supported in bearings 34 at the base of the standards and below the roll 'of pa er 30. The sheet of paper 31 passes over t e roll 32 forward and around a guide roller 35, and from thence passes rearward and over the pressing roll 14 whose face is smooth.

' The 'sheet of paper 28 after it passes the paste applying roller 18 passes between the roller 14 and the roll 13. The sheet 31 is then carried upward and forward over the A rope or other The two sheets of pap)? 30 and 31 are then carried forw. rd and tween pressing plat- @118 r o h r dry sand Pressin do es 6 These pressing platens are not siiown in detail as h y y e. m d in y uit ble manner an are well known in the art.

It will be seen that with the construction, above described proper pressure is seeured between the corrugating 1 Qllsj1 2 and 1,3. by'ad just-ing the screw 8, while proper pressure is secured between the rolls 13 and 14 by adj usting the screw 8, The pressure on the roll 12 is necessa in order to secure a proper corrugation dr the paper, While the pressure on-the bottom roll'is necessary in order to the p a na e? t I p nder n devices are of course provided-to secure a' get a D ap a es n of the r ted p rse dle 24 or a pu ey moantedc here a and thus resist the rotation of the roll 2 8 to a sufiicient degree to place a, preper tension upon the paper. I

Steam is carried into the several rolls by means of steam pipes 39 which are connected to these rolls in a manner well known in.

the art and therefore requiring no description. i

While I do not wish to limit myself to any specific means for rotating the several rolls, I have shown for this purpose the roll 13 as being mounted on a shaft 10 which projects out beyond one of the supporting standards and is provided with a gear wheel 40. This meshes with a gear wheel 41 of the same diameter upon the shaft 9 of the roll 12 and also meshes with a gear wheel 42 upon the shaft 11 of the roll 14. In order to rotate the paste-applying rolls, I provide the shaft of the roll 18 with a gear wheel 43 which meshes with the gear wheel 42. Either one of the rolls 18 or 20 may be. positively driven, however, and the other roll be rotated by frictional contact with the driven roll. The shaft 10 is preferably provided with a ar wheel 44 by which power may be applied to the train of rolls in any suitable manner.
